“Even God cannot change the past.”

“We cannot change the history of the past.”

“The past is the past. You cannot change it, but you can learn from it.”

“… the three things I cannot change are the past, the truth, and you.”

“God cannot alter the past, but historians can.”

“But you cannot change your past, no matter how you craft your future.”

“Therefore, you must never be disappointed in life and you must remember that what even God cannot achieve, you can achieve through hard work. Karma is a thing, which can even change the course laid down by God.”

“What sort of arrogance did she have, even to imagine reaching back into the past and making changes? Who am I, she thought, if I dare to answer prayers intended for the gods?”

“We cannot change the past even if we could go back in time. The fabric of space-time continuum may automatically correct anomalies caused by, say, a time traveler such that any ripple effects are short-lived.”

“But the past cannot be changed, and we carry our choices with us, forward, into the unknown. We can only move on.”
